About the 650 litre water tankThis is our ultimate slimline water tank. Made from a strong plastic called polyethylene that is weather resistant and frost resistant.

To make using our slimline water tank even easier, we pre-mould a 1" BSP outlet in to the bottom of the tank which you can attach a brass garden tap. To give you access inside the water tank we cut and attach an 8" screw down vented lid. This can be used to install a submersible water pump or suction pipe.
